REFRIGERATOR-CAR.

SPECIFICATION forming part of Letters Patent No. 375,191, dated December 20, 1887.

Application filed May iii, 1887.

To all whom it 121.0) 1 concern.-

Be it known that I, GASSIUS CLAY PALMER, a citizen of the United States, residing 'at Painesville, county of Lake, State of Ohio, have invented certain new and useful Improvements in Refrigerator-Oars, of which the following is a specification.

In Letters Patent of the United States No. 290,600, dated December 18, 1883, I described a refrigerating-car upon which my present invention is designed as an improvement.

The first part of my improvement consists in combining with the fan, by which the air is circulated in contact with the refrigerator, a rotating case, whereby the current of air flowing from the fan may be directed either in conheater arranged within the car, or may be directed out of the car into the open air, so that the car may be either cooled, heated, or ventilated.

In the drawings I have not shown the machinery for producing cold nor for driving the fan, since this machinery may be constructed in substantial accordance with said Patent No. 290,600; but I have confined the drawings to showing the position of the refrigerator and heater and of the fan and various flues for conducting the air.

Figure 1 is a longitudinal view of the car with one side removed, so as to expose the interior arrangements of the side of the car at which theheater is situated, or, in other words, a longitudinal view at the sectional line 1 1 of Fig. 3. Fig. 2 is a cross-section on the line 2 2, Fig. 1. Figfl3 is a crosssection on the line 3 3 of Fig. 1, but having the partition in front of the fan cut away, so as to expose the position of the fan, and also with the drum of the heater broken away, so as to show the flues thereof.

a is the body of the car where the provisions are stored.

b is a compartment at one end of the car for the accommodation of the machinery, &c., said two compartments, a and I), being separated by an insulated partition, 0, similarly as shown in said Patent No. 290,600. The refrigerator d, the conduit 0, and the fan f, and the partition g in front of the refrigerator are also all arranged substantially as shown in said patent.

Serial No. 233,578. (No model.)

It is a conduit which leads from one side of the fan out through the side of the car, so as to communicate with the open air.

" i is a conduit which leads from the opposite side of the fan to an opening, 9', in the partition a.

k is a cylinder or drum which is located in the compartment 1), and is connected at its top with the openingj and at its bottom with an opening, Z, leading back into the storagecom partment. Within this drum or cylinder is are placed the fluesm from a heater, which in the drawings is represented as a kerosene-oil stove, a.

In the walls or end of the car, at a distance from the partition '0, preferably near the bottom, are arranged openings q, connecting with the outer air, which openings are regulated by proper valves. The casing 0, which surrounds the fanf, is journaled at each end, so that it may be rotated to bring the peripheral opening in either of three positions either directly downward, as shown in Fig. 2, when the air from the fan will be discharged into contact with the refrigerator, or' to one side, as shown in Fig. 3, when the air will be discharged into the conduit 1', or to the opposite side, when the air will be discharged into the conduit h.-

The arrangements which I prefer for making provision for the turning of the fan-casing are shown in detail in Fig. 4-,where it will be observed that the casing at one end is journaled on the mouth of the conduite and at the other end is journaled upon the shaft of the fan.

The operation of the above-described structure is as follows: Where it is desired to refrigerate the storage-compartment a the easing of the fan is adjusted as in Fig. 2, and the openings in the side and ends of the car are closed. The operation of the fan then draws the air into the conduit 6 from the top of the storage-compartment and discharges it down ward from the casing of the fan around the pipes of the refrigerator d, whence it is dis charged at the bottom of the storage-compartment, as, described in said former patent. When it is desired to heat the storage-compartment, as will sometimes be the case where articles likely to be frozen are carried in cold weather, the casing of the fan is turned so as to discharge the air into the conduit 2'. With this adjustment the air is drawn from the storage-compartment into the conduit e and discharged by the fan into the conduit i,from which it is conducted through the openingj into the drum or cylinder 70, wherein it is heated by the flues n, and thence through the opening Z back again into the storage-compartment near the bottom, so that a constant current of warm air is maintained in the storage-compartment. In such case of course the refrigerator d is not in use.

When it is desired to ventilate the compartment a, as is sometimes the case for purification or for the removal of gases generated therein, the valves in the opening (1 and the conduit It will be opened and the casing of the fan turned so as to discharge the air into the conduit 71. Under this adjustment the fresh air will be drawn from the outer atmosphere in at the opening (1, thence through the storage-compartment-,and into the conduit 6. The fan then discharges it through the conduit it into the open air. Under these circumstances it will be seen that neither the refrigerator nor the heater are in use, but that a current of pure outside atmosphere will be circulated through the storagecompartment.

I claim- 1. A provisioncar containing the compart ments a and b, separated by the insulatingpartition 0, the refrigerator (1, located within said compartment a, the heater 7.", located within said compartment b, the fan fand its casing 0, the passage 6, leading from the chamber a to the fan, the passage 2', leading from the fan to the heater, the passage Zleading from the heater to the chamber a, a passage leading from the fan to and around the refrigerator, and means whereby the passages from the fan to the heater and from the fan to the refrigerator may be respectively closed, all substantially as described, whereby by the opening or closing of the passages, respectively, the chamber a may be alternately refrigerated or heated.

2. A provision-car containing an insulated compartment,a, the refrigeratorlocated within said insulated compartment, a fan and fancasing, the passage 0, leading from the compartment a to the fan, a passage leading from the fan to and around the refrigerator, the passage q, leading from the external air to the eompartmenta, thepassage 71,leading from the fan to the external air, and means whereby the passages from the fan to the external air and 'from the fan to the refrigerator may be respectively e1osed,all substantially as described, whereby by the opening or closing of the passages, respectively, the compartment a may be alternately ventilated 01*.refrigerated.
